The Mining Process - Newmont Corporation

We introduce air bubbles to the slurry while it is in small tanks, called flotation cells. We add some chemicals to the slurry to assist the process. The desired minerals stick to the bubbles and rise to the top, resulting in froth. The froth overflows from the tank, and is removed and sent to the next step in processing. Gravity Circuit

Open Pit Mining - an overview ScienceDirect Topics

An open pit mine is typically excavated with a series of benches to reach greater depths. Open pit mining initially involves the removal of soil and rock on top of the ore via drilling or blasting, which is put aside for future reclamation purposes after the useful content of the mine has been extracted. The resulting broken up rock materials are removed with front-end loaders and loaded onto dump trucks, which then

A process for reducing rocks and concentrating heavy

To obtain minerals suitable for age-dating and other analyses, it is necessary to first reduce the mineral-bearing rock to a fine, sand-like consistency. Reducing whole rock requires crushing, grinding, and sieving. Ideally, the reduced material should range in size from 80- to 270-mesh (an opening between wires in a sieve). The openings in an 80-mesh sieve are equal to 0.007 inches, 0.177 ...
